Abstract: In one embodiment, a method includes accessing a notification to be sent to a user, where the notification has a context. The method also includes sending a request to a history service for historical notification data associated with the user with respect to the context of the notification and a ranking of the notification where the ranking indicates a probability of the user interacting with the notification. The method also includes receiving the historical notification data and the ranking from the history service. Moreover, the method also includes determining a delivery policy to apply to the notification based at least in part on the context of the notification, the historical notification data, and the ranking. Furthermore, the method also includes applying the delivery policy to the notification to be sent to the user.
